摘要： Resins of high shock resistance when shaped as tubes, rods, plates or the like are prepared by dissolving a copolymer of vinyl acetate and ethylene in liquid vinyl chloride, partly polymerizing another quantity of vinyl chloride with high turbulence in mass, mixing the solution of vinyl acetate-ethylene copolymer and the suspension of polyvinyl chloride in vinyl chloride, and subjecting this mixture to conditions of temperature, pressure, agitation and catalysis favorable to graft polymerization in mass of vinyl chloride on the vinyl acetateethylene copolymer.
